Now decide how many days worth of energy you want to store in your battery bank.  It is normal to match a 12 V battery bank to a 400 W power system.  Example: You want the battery bank to last three days without recharging and that you use 5.0 kwh per day.  Note: Colder temperatures have a negative effect on the capacity of your battery bank.  Now if you divide by your battery's rating you find the number of batteries you must use.  To determine the inverter size we must find the peak load or maximum wattage of your home.  If your battery bank is always indoors in a heated area then you don't have a problem.  Note: All calculations assume only a 50% discharge to your batteries to optimize battery life.  Also include Battery Capacity for your Home Power Systems.  Use these handy calculator to help decide which system size is right for you.  You can calculate the Exact Number of Solar Panels You Need For Your Usage Plus the Space you need.  Solar Panel Calculator Plus calculate custom Off-Grid Solar Home Power Systems.  The most typical solar panel size used for residential installations is 65 inches by 39 inches.  Multiply the wattage of each device by its run-time to get the energy in watt-hours per day.  A 5 kW system would work most appropriately with a 48 V wiring system, in order to decrease current flow in the wires.  The sum will tell you which inverter size you need.  As 5.0 x 3 x 2 = 30.0kwh, this is the energy we need from the batteries.  But if they're stored in an unheated area during the winter then you'll need to account for this.  Example: A room has two 60 watt light bulb and a 300 watt desktop computer.  Converting this to AH we have to divide by the voltage of your system.  The larger the system you have, the higher the voltage you should have.  The inverter size is 60 x 2 + 300 = 420 watts.  Example: Light bulbs run for 5 hours a day.  This is found by adding up the wattage of the appliances and devices that could be run at the same time.  And the wattage output range from 200 - 330 watts.  Find the energy used in a day.  Figure out how long each electronic device will be run in hours during a day.  If we choose to use 48V, the minimum AH capacity is then 30 000/48 = 625 AH.  Include everything from microwaves and lights to computers and clocks.  Computer runs for 2 hours a day.  Multiply with 1.2 or 1.5 into a safe area.
